Hi everybody, I have a doubt about my proper using the tool Axes for measuring angle between helices. After aligning two model and generating the axes corresponding to the helices of interest, I select them in the 'Structure Measurements' dialog windows. As you can see from a snapshot, they look properly selected. They are almost overlapping, but in the Reply Log I get the following info: col_best_001.pdb helix 10/col_best_005.pdb helix 2 crossing angle: 36.9 degrees, distance: 15.3 angstroms Beside the value of the angle seeming to me too high, shouldn't the distance between the helices be within few angs (at least according to how I interpret the documentation)? Probably I am missing something. Thanks in advance, Giovanni Cardone
